10.3.3 Water cooling maintenance (option K2)
Pre --- condition: Machine switched off.
Mains isolator locked off
Machine cooled down.
Check the cooler regularly for leaks and contamination. Frequency of checking is depend-
ant on the characteristics of the cooling water.
Contamination causes overheating and machine damage.
Observe the airend discharge temperature to detect any tendency to rise.
Cleaning:
An authorised KAESER service agent should clean the cooler when the airend dis-
charge temperature is 10 ˚ C above the annual average.
Leakage
Pressure in the cooling oil circuit is generally higher than that in the cooling water system.
If a leak occurs, oil will run into the cooling water.
Check the cooler visually for leaks.
Have an authorised KAESER service agent check the cooler for internal leaks at least
once a year.
